I had a similar experience with failed update, on the first try. The download seemed to go alright, and I clicked install, walked away for a moment, came back, and the PlayBook had rebooted and was still running 1.0.3.

I ran the update a second time and watched the PlayBook the entire time. The install ran to 100% and I got the restart button. Clicked restart. Now running 1.0.5.

I guess the install aborted the first time. Interesting the failed install didn't mess up the device software when it went south. Cool.

Obviously, staying with the PlayBook and staring at it the entire time is what did the trick.Posted via BlackBerryForums.com Mobile
